SK hynix shelves Solidigm’s U.S. IPO as Seoul’s regulator raises dual-listing questions

SK hynix said on October 23 that its U.S. subsidiary Solidigm will end its review of a potential pre-IPO fundraising and a U.S. listing, according to the company’s newsroom statement. CNBC reported that SK hynix shares fell as much as 3% in Seoul.

What SK hynix says it is stopping, and why

The statement says the move follows a look at recent capital market conditions and share price trends. In the company’s words, “Solidigm will halt its review of potential pre-IPO and IPO options.”

SK hynix stresses that the decision is not a retreat from the business. It says the move “does not reflect any change in Solidigm’s growth prospects or investment needs”, and that expanding production capacity and strengthening competitiveness remain priorities. The company says it will keep exploring other ways to finance a new U.S. semiconductor fabrication plant, as demand for AI memory grows.

CNBC reports that SK hynix had seen an IPO as a way to fund Solidigm’s expansion and give it more room for shareholder returns such as dividends and buybacks. According to CNBC’s account of the statement, the company also said market volatility had added to a broader correction in chip stocks, and that it needed to reassess whether a listing would benefit existing shareholders. It also said Solidigm’s current plants have limited capacity to meet AI-driven memory demand.

A regulator and shareholders were already pushing back

The announcement does not mention regulators, but the timing matters. CNBC, citing Reuters, reports that South Korea’s financial regulator said earlier this week that a U.S. listing of Solidigm could breach the country’s rules on dual listings. The Financial Supervisory Service governor, Lee Chan-jin, said officials were checking whether the IPO would need a review under rules meant to protect minority shareholders. These are the regulator’s reported views, and SK hynix’s statement does not say they drove its decision.

Shareholder concern predates this week. On October 1, SK hynix said it had made no decision on a listing and would weigh the effect on existing shareholders, according to the Korea Times. Search coverage of that period also shows the Korea Corporate Governance Forum calling for listing talks to be suspended, describing the plan as a duplicate listing.

What the pullback means against a $150 billion talking point

The scale of what was on the table explains why the reversal is notable. In late September, Reuters reported, citing three sources, that Solidigm was weighing an IPO that could value the unit at up to $150 billion, possibly as soon as next year, and that the plans were at an early stage (Reuters report, via WHBL). SK hynix never confirmed those figures, and the October 23 statement gives no valuation or raise size.

The market backdrop is weak. CNBC says the Nasdaq Composite fell 2.6% on Thursday, its worst session since June, with Nvidia down 4.4% and AMD down 8.1%. CoreWeave dropped 10% that day, extending its monthly decline to 36%. Nvidia CEO Jensen Huang told CNBC he does not expect a memory chip oversupply by 2029, despite concerns about weaker demand.

For readers following the AI trade, the point is that memory makers are still trying to fund capacity, while public markets are less welcoming to AI-linked listings than they were a few weeks ago. Our look at what is known about the Anthropic IPO covers another large AI-related listing that depends on investor appetite holding up.

What the statement leaves unanswered

SK hynix does not say how it will pay for the new U.S. fab, how much it needs, or when it would revisit a listing. It says only that it will keep exploring alternatives. The company also does not describe the decision as permanent; it says the review is being halted. The 3% drop is CNBC’s description of early Friday trading in Seoul and may not reflect where shares closed.

Solidigm’s customers see no direct change for now: the statement describes no change to products or existing production. The open question is how, and how fast, the extra U.S. capacity for AI memory gets financed without a listing.
